Plants possess a fascinating ability to communicate with each other through a complex system of chemical signals. Aboveground, they use airborne volatile signals to attract predatory insects, prime defenses in neighbors, facilitate nutrient transfer, and promote plant interactions. However, less is known about the chemical signaling that goes on underground. In this Perspective article, Guerrieri […]
Cellular metabolism involves flux through metabolic routes, which can be measured using stable isotope (13C,15N) tracers. High-resolution mass spectrometry (HRMS) and transient isotope labeling studies offer an opportunity to get an in-depth understanding of metabolism in specific contexts. In this new work, Kambhampati et al. introduce Stable Isotope-assisted Metabolomics for Pathway Elucidation (SIMPEL) as a […]
Amino acids (AA) are fundamental components of peptides, proteins, and enzymes that play a critical role in plant growth, cellular metabolism, and stress response. Plants synthesize most AA within chloroplasts and require membrane transporters to transfer them from stroma to cytosol. Cytosolic AA are essential for synthesizing proteins and provide nitrogen support for the growth […]
Plants shape ecosystems and sustain human life. Only a small portion of plant diversity is currently known to be in use, even though most plants may be useful to humans. Over time, certain species become widespread, but others are native to specific geographical regions. Thus, to manage plant resources efficiently and sustainably, people must understand […]
